Cant afford the Diesel pusher market in the class A motor home market, but would consider the new 6.0L in a class C E-450.The improved V-10 seems to offer whats neebed to move vehicles in the 12,000lbs-22,000lbs weight range.So I guess it comes down to initial cost difference between engines,cab noise,fuel economy,maintenance,fuel cost and maybe resale.Its good to see that Ford can still tweak the smaller 6.8L to out power the bigger 8.1L
